Hard Disk vs Hard Drive | Hard Disk vs Hard Disk Drive
Hard Disk Drives yog cov khoom siv thib ob feem ntau siv hauv kev siv. Nws muaj peev xwm loj dua thiab ua tau zoo dua piv rau cov txheej txheem ua ntej xws li cov kab hlau nplaum thiab cov ntawv xuas nrig ntaus.
Hard Disk Drive (HDD) / Hard Drive
Ib lub hard disk drive (HDD) yog cov ntaub ntawv thib ob uas siv los khaws thiab khaws cov ntaub ntawv digital hauv computer. Taw qhia los ntawm IBM hauv xyoo 1956, hard disk drive yog qhov tseem ceeb thib ob cia khoom siv rau cov khoos phis tawj dav dav thaum xyoo 1960s thiab tseem yog daim ntawv tseem ceeb ntawm kev khaws cia. Cov thev naus laus zis tau txhim kho zoo txij li nws tau qhia.
Ib lub hard disk drive muaj cov hauv qab no.
1. Logic Board - tus tswj Circuit Court board ntawm HDD, nws sib txuas lus nrog cov processor thiab tswj cov khoom cuam tshuam ntawm HDD tsav.
2. Actuator, Lub suab coil thiab lub cev muaj zog - tswj thiab tsav lub caj npab tuav lub sensors siv los sau thiab nyeem cov ntaub ntawv.
3. Actuator Arms - ntev thiab daim duab peb sab hauv cov hlau zoo li lub hauv paus nrog rau tus actuator, nws yog cov qauv tseem ceeb txhawb kev nyeem-sau taub hau.
4. Sliders - tsau rau qhov kawg ntawm lub caj npab actuator, thiab nqa cov ntawv nyeem sau taub hau hla cov disks.
5. Nyeem / Sau Lub Taub Hau - sau thiab nyeem cov ntaub ntawv los ntawm cov hlau nplaum disks.
6. Spindle thiab Spindle Tsav - lub hauv paus sib dhos ntawm cov disks thiab lub cev muaj zog tsav lub disks
7. Hard Disks - tham hauv qab no
Lub hard drive yog qhov tseem ceeb vim lawv lub peev xwm thiab kev ua haujlwm. Lub peev xwm ntawm HDDs txawv ntawm tsav mus rau lwm qhov tab sis tau nce zuj zus mus ib ntus. Feem ntau, lub PC niaj hnub siv HDD nrog lub peev xwm hauv TeraByte ntau yam. Rau cov khoos phis tawj hauv cov haujlwm tshwj xeeb xws li cov chaw khaws ntaub ntawv siv cov hard drive uas muaj peev xwm ntau dua.
Qhov kev ua tau zoo ntawm lub hard drive yog tus yam ntxwv los ntawm Lub Sijhawm Nkag Mus, Kev Sib Hloov Ncua, thiab Hloov Ceev. Lub sijhawm nkag mus yog lub sijhawm siv los pib lub actuator los ntawm tus maub los kom txav tus actuator caj npab nrog cov nyeem / sau taub hau rau hauv txoj hauj lwm hla txoj kev zoo. Rotational ncua yog lub sij hawm nyeem / sau taub hau yuav tsum tau tos ua ntej lub hom phiaj sector / pawg rotates rau hauv txoj hauj lwm. Hloov ceev yog cov ntaub ntawv tsis thiab hloov pauv tus nqi ntawm lub hard drive.
Hard drives txuas nrog lub rooj tsav xwm loj uas siv ntau qhov sib txawv. Enhanced Integrated Drive Electronics (EIDE), Me Me Computer System Interface (SCSI), Serial Attached SCSI (SAS), IEEE 1394 Firewire, thiab Fiber Channel yog lub ntsiab interfaces siv nyob rau hauv niaj hnub computer systems. Feem ntau ntawm cov PCs siv Enhanced Integrated Drive Electronics (EIDE) uas suav nrog Serial ATA (SATA) thiab Parallel ATA (PATA) interfaces.
Hard Disc Drives yog cov tshuab tsav nrog cov khoom txav hauv lawv; Yog li ntawd, dhau sij hawm thiab siv sij hawm ntev hnav thiab tsim kua muag tshwm sim, ua rau lub cuab yeej siv tsis tau.
Hard Disk
Hauv cov hard disk drives, cov ntaub ntawv khaws cia siv nrawm nrawm (platters) coated nrog cov khoom sib nqus, uas feem ntau hu ua Hard Disks. Ib qho HDD muaj ib lossis ntau dua cov khoom sib hloov, uas yog hu ua platters. Cov disks no tuaj yeem muab tso ua ke los tsim ib pawg, uas tso cai rau ntau qhov chaw ntawm cov disks. Sib nqus nyeem-sau taub hau teem rau ntawm lub txav actuator caj npab nyeem thiab sau cov ntaub ntawv rau ntawm qhov chaw.
Qhov txawv ntawm Hard Disk thiab Hard Disk Drive yog dab tsi?
Hard Disk yog ib qho khoom siv thib ob uas siv cov hlau nplaum sib nqus los khaws cov ntaub ntawv. (Lub cuab yeej ua tiav chav tsev hu ua HDD lossis Hard Disk Drive). Cov disks uas cov ntaub ntawv sau yog hu ua Hard Disks.
